Title: Method and apparatus for transmitting broadband amplitude modulated radio frequency signals over optical links
Inventor: PIDGEON REZIN E JR
IPC: H04J14/02
Filed: 1990-11-21
Granted: 1996-08-13
Abstract: A plurality of radio frequency channels are separated into two or more contiguous groups of channels, each of such groups occupying less than one octave. A first group of channels occupies a 54 MHz to 106 MHz band, a second band of chan-nels occupies a 108 MHz to 214 MHz band, and optionally, additional channel groups may occupy the bands of 214 MHz through 426 MHz and 426 MHz through 850 MHz. Each sub-band is used to modulate the intensity of the output of a laser (1, 2, 3). Each resulting amplitude modulated light signal is transmitted over an optical link (F1, F2, F3, F4) to a receiving location.  Alternatively, the lasers (1, 2, 3) may be selected to generate light at different wavelengths with all outputs transmitted over a single optical link.  At the receiving location, each of the optical signals is received and demodulated by a re-spective individual receiver (51, 52, 53).  The demodulated signal is passed through a bandpass filter which reduces harmonics, in-termodulation distortions, and noise produced in transmission.  The resulting signals are then matched in amplitude before being applied to combiner (69, 70) which converts them back into a single broadband signal.  The broadband signal is then processed to reduce discontinuities at the transitions between the sub-bands.  All of the baseband television signals can be modulated onto car-rier frequencies in the highest sub-band of interest (e.g., in the range of 330 to 550 MHz).  Because of the separation of signals provided by multiple optical links (F1, F2, F3, F4), the same carrier frequency may be utilized on each of the links to carry a channel of baseband video information.

Title: Method for tachycardia discrimination
Inventor: LANG DOUGLAS
IPC: A61B5/0452
Filed: 1993-05-18
Granted: 1997-10-21
Abstract: A cardiac discrimination method in which feature values of a heart related signal (e.g., cardiac biopotentials) determined to be non-baseline are compared with feature values of a heart related signal determined to be normal baseline.  The feature values are extracted on an event-basis (a periodically), for obtaining feature values of a complex.  For each complex, the feature values form a sequence with the value having the largest absolute value for the sequence given special identity as a fiducial point.  The normal baseline complexes'  characteristic sequence and a  non-baseline complex's sequence are aligned according to the fiducial points, and unoccupied positions on the ends of the sequences resulting from the alignment are filled with zeros to create normal baseline and non-baseline vectors.  The similarity value and dissimilarity value of the normalized non-baseline vector with respect to the normalized normal baseline vector are determined.  The type of tachycardia (VT or non-VT) and consequently the selection of appropriate therapy are determined  by  the  location  in  a  discrimination  plane  of  a discrimination point, the coordinates of which are equal to the similarity and dissimilarity values.  In addition, the location of a similarly generated hemodynamically discrimination point can be used to discriminate hemodynamically stable and unstable tachycardias based on the features derived from events in hemodynamic related signals.  Furthermore, physiological indicators may be processed in a similar manner to determine an ideal rate at which the heart should be paced by a pacemaker.
